The correct answer is: D. Stretcher bond is generally used for the construction of brick corbel.
A corbel is a structural element that projects from a wall and supports a load. It is typically made of brick, stone, or concrete. The maximum projection of a corbel should not be more than the thickness of the wall, and the maximum projection of each corbel course should be limited to a quarter brick at a time. Discontinuous corbels are used to carry heavy concentrated loads. Stretcher bond is a type of brick masonry bond in which all the bricks are laid in a horizontal position. It is not a suitable bond for the construction of brick corbels, as it does not provide the necessary strength and stability.
Here is a diagram of a brick corbel:

The corbel is made up of a series of bricks that are laid in a stepped fashion. The bricks are held in place by mortar. The corbel projects from the wall and supports a load.
